This invention relatesto book staplingmachines and the principal objectistoprovide generally a highly simplified and improved I machine forstapling booklets andthe'lilr'e, so

designed and arrangedthat the staplingop- .er'ations may be greatlyfacilitated and substantial economies effected over-obtaining methodsand machines;

An important ob ect's topro'vide improved wire feeding, forming,cutting, driving and clinching means cooperatively arranged foraccurately forming staples ofuniform length, together with means forcommonly adjusting said elements for'varying the lengthof wire cut andstaple formed and clinched at each operation, to correspond to thevarying thickness v of books desired to be;stapled; v

;Another object is to provid ter forthe wire so mounted and disposedwith respect to the wirethat the cutterwillmake rolling contact with thewire in a-cutting op eration, through ashearingaction, and pre- 1 .sentdifferent portionsof the cutter to the successive portions of wire, thuslengthening the life of the cutter over that of commonly usedreciprocating cutters.

A further object 1s to provide a wire feeding mechanism arranged topositivelyfeed the wire at intervals to stapling position, in uniformlengths, and readilycapable of adjustment for varying the lengthof wirefor the staples.

Itis also an object'to provide an improved and accurateiormingdevicewhereby the sec tions. of wire cut for the staplemay beneatly' andaccurately formed while positively held in suitable uides, preparatoryto' a.driving operation, together with improved means for driving thestaples through a substantial number of vsignatures, andforolinchingaand bendin the ends of the staples upwardly,

at the completion of an operation:

A still further object is to provide a novel and efi'icient form ofstapling table for supporting and holdingthe work during a staplingoperation, and capableof adjustment to horizontal and angular planes, atwill,-'for fiat and saddle stitching. i 1 Other and. more detailedobjects of invena rotary cutsimilar vlew above, during aclinchingoperation;

. in general conformity tamachines now in use for similar purposes, andembodles many well known and generally used expedients.

It is, however, materially different with respect t-ojt-h'e particularfeatures herein'before mentioned in the objects of invention andincludes substantial improvements over'the art which have proven tobeexpeditious and economical in time and labor, in stapling work. haveshown :in' Fig. 1 an accredited form and design of standard S on whichthe oper- "ating'me'c'hanism is supported, for the rea- "son that .sucha form of device lends itself conveniently to the necessities ofstapling operations. Said standardhas a base B and a head integrallyformed with the supporting :column C, and rotatably carries in the headH a driving "sh'aft D with a pulley P on the rear end thereof, arrangedfor operation by means of a belt P, or otherwise, adapted for connectionwith a motor or line shaft, not shown.

A suitable form of clutch A is provided on shaft 1) whereby said shaftis controlled in operation, for intermittently and at will applyingpower to the machine. The clutch A is operated by a pedal E oscillatablymounted on the front portion of base B and connected by means of rods 1and 2, or other suitable means with said clutch. These con nections arenot material to my invention and any suitable clutch and operating meanstherefor may be employed in connection with my improvements.

Shaft D is suitably journaled at 3 in the rear portion of head H and atthe front thereof in a suitable bearing formed on a partition 4 at therear side of an enlargement .H integral with head Shaft D extendsforwardly into a cam recess 5 in portion H and carries an internal cam Fhaving an irregularly formed slot f in the front side thereof.Rearwardly'of cam F, I provide a wire feed roll-er R which is fixed toshaft D and has its periphery 6 formed in registration with the pitchline of a gear G integrally formed on the rear portion of the roller.

On the rear side of portion H of head H, I provide a cooperating rollerR and gears G of the same size and character as roller B, which isdriven by the meshing of gears Gr and G. The roller -R is rotatablycarried on an arm 7 by means of a bolt 8 secured to the central portionof said arm, while the outer end 9 of the arm is pivotally mounted ona'lug 1O integrally formed on the head H and isheld by means of a bolt11 through said lug. V i

The rollers'R and R are held in operative engagement by means of atension spring 12 connected with the free end 13 of the arm, and at itsother end by suitable means to the rear portion of the head H. Roller R,as shown in Figs. 11, 13 and 14 has an arcuate enlargement 1" formed onthe periphery thereof, and co-incident with the pitch line of the gearsG and G. The edges 15 and 15 of said enlargement are tapered as shown inFig. 11, so as to provide an adjustable feed for the stapling wire Wwhich is held be tween said rollers, as hereinafter described. Thewireis carried on a straightener I at tached to a bracket 71 which issecured by means of one or more screws 16 to the pe riphery of the-headportion H, as seen in Fig. 40. Said straightener includes a plurality of'annularly grooved rollers 17, 17, -etc., arranged as shown in Fig. 40to receive the wire therebetween, a supply of said wire being carried ona reel J rotatably mounted on-a spindle 17.

The reelJ is held against excessive rotation by means of a frictionspider 18 which is adjustable on the'spindle17f by meansof nuts,19;..Thewire; Wis fed from the reel J outwardly and over'a curved andinclined guide-way K, downwardly between the rollers'17 in thebracket-I. 2' The central rollerv 17 is adjustable bymeansofa set screw19 in the bracket I'with respect to the other of said rollers. The-wire.,from the straight ener I is fed downwardly through a wire'feedadjustment device L, as shown in Fig. 11 and v between the rollers R andR.

Said adjustment device is attached to the rear of the housing portion Hcentrally between the rollers R andR",' and'includesa 'slide' 20 whichis, mounted on axfixed base 21. Said slide has a bifurcated forwardportion overlying the roller R with the fur-- cations 22and 22 spacedequidistant on opposite sides of the center of said roller.

'20 and=22 are pierced-ftransverselyyto receive and hold thefends ofwire: carrying. tubes 23.

J :The forward ends of the furca-tions 22 and 23', respectively, forguiding the wire through the. arms 22 and 22and between the peripheriesofthejrollers R and R. I Said tubes 23 and 23 terminate in-sle'eves 24and 24- having beveled inner ends, and the outer ends of which engagethe inne'rffaces of the: arms 22 and 22, respectively.

The slide 20fhas a reduced portion is slidably held in a 'guide-way 25formed in the supporting member ,21, and a compression spring 26'isrc'a'rried. in a recess 26"- of. the body 21 which is adapted tocompress against apin 27 which iscarried in the portion 25 of the slide20 and projects into the recess 26". Thus as the slide 20 is movedlongitudinally as seen Fig. 11, the por-' tion of the .wire W betweenthe sleeves 24 and 24- will move longitudinally overlthe periphcries ofthe rollers Rand R.

T The shaft 36 carries a lever-57 with a horiunderlying the forming.head and adaptedto ":zonta-lly disposed arm 5,8 having aroller 59 whichengagesa groove .60 formed between ribs .61 iand 62 on the front faceofportio'n" V 47 of memberjM; Member57 is clamped on Lug 37Qcarries adepending. arm 43 pivoted 9" at 44 to the outer end of .saidilug,andalso pivotally connected at its lower end 45 with V shaft 36 by meansof a screw 63 extending through lugs 64, 64.

The upper rib 61 on member M has a boss 65 which extends outwardly frommember M and beneath a corresponding boss 66 formed on the standard S,bosses 65 and 66 constituting a gauge between which a book is adapted tobe placed while the member M is adjusted vertically on the standard S,for indicating the proper operating positions of the clinching head Nand the forming and driving head 0.

It will be apparent that the movement of the member M will cause apivotal movement of the arm 57 and shaft 36 as the bosses 65 and 66 arespreadapart or moved in the direction of each other, and thecorresponding movement of shaft 36' will effect a rocking movement ofarm which is connected with the wire adjustment devices L and the arms39 and 43 which are connected with the forming head O. Thus theadjustment of the member M at the same time and to a correspondingextent establishes the feeding relation of the rollers R and R, theproper elevationof the clinching head N and the move- -ment of thecutter and the length of wire to be cut thereby, as will more clearlyhereinafter appear.

The clinching head N comprises a block 67 having a groove 68 verticallydisposed therein in which a clincher blade at is movably held. The blockis removably held on the upper end portion 69 of member M by means ofscrews'68 as seen in Figs. 16 and 17 The clincher n is connected bymeans of a rod 7 O at a point 71 with a bell crank 72 which is pivotedat 73 in the forward portion of the adjustable member M. l

Said bell crank has a depending arm which is pivotally connected at 7 4with a horizontal rod 75 extending rearwardly under the portion ofmember M and guided in alug 76 depending therefrom. Rod is pivotallyconnected at 77 with the bell crank 78 which is ivotally mounted at 79within the standard Said bell crank has its other arm pivotallyconnected at 80 with a vertical rod 81 rearwardly of the column S andguided in a lug 82 on the rear side of said column.

Fixed to the drive shaft 1) between the clutch A and the column S, Iprovide a cam 83 which has a peripheral enlargement 84 thereon adaptedto engage the-upper end 85 of rod 81, so that when the cam is rotatedthe portion 8 will depress said rod 81, and through the connectiondescribed elevate the rod 7 O and the clincher n, for the purposeofclinching the staples which have been pre-.

viously driven through the book or matter indicated in Figs. 16 and 17.

The block 67 of the clincher has oppositely beveled portions 69', 69formed in theupper side thereof and communicating with the groove 68 inwhich the clincher operates, while the clincher is provided with ahorizontal groove n on the upper end thereof in registration withreceiving the ends 6, e of'the staples as shown in Figs. 19 and 20,whereby the ends of said staples may be clinched on the matter X at thecompletion of a driving operation.

The front arm 56 of member M is arranged to adjustably support a table Tcomposed of a pair of leaves 25 and t hingedly connected at a pluralityof points 86 at their inner edges, theaxis of said table being alinedwith the clincher n. The opposite sides of portion 56 of member M' areprovided with alined bosses 87 and 87 in which is carried a shaft 88having fixed thereto at its opposite ends arms 89 and 89. The upperedges of said arms are'pivotally connected at 90 and 91 with a pair ofdiagonally disposed arms 92 and 92 which arepivotally attached at theirupper ends at points 93 and 93"00 depending lugs 94 and 94',respectively from leaves 25 and t,

The pivot pin 90 is slidable in the arm 89' and is adapted toselectively seat in a pair of perforations above and below the shaft 88in the portion 56 of member M for holding the table T in either of thetwo positions shown in Fig. 2.

When it is desired to dispose the table as shown in broken lines in saidfigure, the pin 90 is withdrawn from its seat in the portion 56 and thearms 89 and 89 are turned on their'axes 88, until the pin occupies theposition as at 90' below the shaft 88, where it may seat in aperforation in the portion 56 and hold the table leaves 25 and tdisposed at substantial angles with respect to each other, as shown.This adjustment is desirable for adapting the machine to different kindsof stapling operations.

Where a plurality of sheets are stapled together at corresponding edgesthe horizontal table is employed, and where the sheets are stapled inthe center at points intermediate their edges, which operation is knownin the trade as saddle stitching, the table T is disposed as indicatedby broken lines in Fig. 2, with the leaves t and i at angles withrespect to each other. 7

The forming and driving head 0 includes formers U and U, a driver V, anda cutter Y,

mounted in operative relation as a unit. Said the beveled portions forhead includes a supporting block 95 stationarily held on adependingportion 96 of the head H by means of screws 97, 97 etc. i

The portion 96 of the frame has a vertical groove of rectangular crosssection, as at 96' to slidably receive a vertically reciprocableformingelement U, which cooperates with a pivotally mounted cooperatingforming element U, as shown in Figs. 24 and 26. The

member U is provided at its upperend with a plate 98 carrying a pin 99on which is mounted a roller 100 whiche'ngages the cam slot fz-in'the'acam E, :for' 'reciprocati'ng themember-:U duringzthe operationofisaid cam; The member U is provided with a vertical guidej way" 101 in'which the driver V is re'cip- 5 rocably mounted.- Saiddriverisipivotallyconnected at its upper "end with a connecting. rod l02 by'means of a pin103; and said con necting rod: is" connected at 104' with the centralportion'lOa 0t cam F bymea-n's of aiscrew m 106: Thus the memberSU'and- V arefidif ferentia'lly reciprocated vcliiring the-operation ofthe cam'F. r

Said member is cut away at 129 so that the wire Vwill overlie the portion 129 when it is fed under the driver V andthrough the cutter block 130.

The member 129 carries a plate 131 attached thereto by means of a screw132 above the portion 129 thereof, to which is attached a fiat spring133 by means ofa screw 134. Said spring has a depending portion 135 withan outwardly beveled portion 136 overlying the portion 137 of the plate131. The portion 135 of the spring is resilient so that the wire V whenfed between the portion 135 of the spring and the portion 137 of saidplate will be frictionally supported in position during and subsequentto the cutting operation, and until engaged by the formingmembers U andU for forming the cut sections of wire into staples. This device isimportant in that it serves as a retainer for the sections of wire W andprevents the accidental dropping thereof from forming position beforethey are gripped and held by the forming members U and U. The member Uis cut away at 138 on one side to slidably engage the portion 137 ofplate 131 which is carried on the gib 128.

a The cutter head Y includes the block 46 which is suspended on the arms39 and 43, shown in Fig. 40, and a detachable block 46 secured theretoby means of one or more screws 140, as shown in Fig. 6. The cutter block46 pivotaly carries a'rotary cutter 141 which is mounted on an arm 142carried on a pin 143 whichextends through the block 46.

" The pin 143 is fixed to the arm 142 at its inner end and is providedon its outer end with a pair of lock nuts 144 by means of which thecutter 141 may be adjusted relative to the inner end 145 of block 46,through which the wire V is fed, as shown in Fig. 5.

The cutter 141 has a beveled edge 146 which movably engages the end 145of block 46 and is also provided with a hub 147 which is pivotally heldin the portion 148 of arm 142. Said arm has an upwardly extendingportion 149 which pivotally carries a roller 150 on a pin or screw 151.The roller 150 is positioned adjacent a recess 152 in the side of theforming member U, and is adapted to engage the lower beveled end 153 ofa rib 154 formed on said member U, so that as the member U movesdownwardly the beveled edge 153 thereof will engage the roller 150 andmove the cutter 141 downwardly over the inner end of passage 155 throughwhich the wire V is extended. Said passage is centrally formed in ahardened steel bushing 156 held in the lower portion of block 46' bymeans of a set screw 157 or otherwise. At the outer end of the bushing156 I provide a larger bushing 158, similarly held by a set screw 159and having an eccentrically formed passage 160 therein, in which is heldby suitable means the lower end of the wire feed tube 31.

The bushing7158is rotatably adjustable in a counter bore 161 inthe block46, for the purpose of varying the relations of the wire passage 162therein with respect to the passage 155 in the bushing 156, so as toincline the wire W at the end of the cutter to a desired extent,upwardly or downwardly for proper engagement with the retainer 136 inthe form the spring 133 shown in Fig. 21.

The cutter 141 is normally held upwardly in the position shown in Fig. 7by means of a spring 163 attached at one end to the screw 151 of the arm142, and at its other end attached to the lower portion of arm 39, whichmovably supports the cutter block in conjunction with the arm 43.

Referring to Fig. 21 it will be noted that the gib 128 is spaced to theright from the forming member U for a substantial distance, and the wirefeed mechanism shown in Figs. 39 and 40 may be adjusted so that the endsof the portions of wire cut for the staples may be extended on oppositesides of the member U for equal distances, so that the ends 6, e, of thestaples will be substantially of the same length. 7 V

In operation, when a reel of wire as at J is properly positioned on themachine, as shown in Fig. 40, and is threaded over the guide K betweenthe rollers 17 of the straightener, between the rollers R and R andthrough the tube 31 downwardly to and through the cutter block 130.' Themachine may be adjusted simultanenously in a single operation forstapling matter of a given thickness, as hereinbefore described.

The table T on which the matter is held in a stapling operation may beadjusted as shown in Figs. 1 and 2 with the leaves horizontally or'angularly disposed, depending upon the character of the matter to bestapled. Thereafter when power is applied to the driving pulley P, saidpulley will operate on the drive shaft 1) without communicating power tothe machine until the pedal E is operated for communicating power inter;

' cutter, effects the operation of the cutter 141 for cutting the wire Wat the .inner end of the'bushing 156.

Immediately tion, the continued movement of the forming member Udownwardly serves to form the .cut section of wire, in the grooves .118,118 of member U, and overthe forming head u of the pivoted formingmember U. At the completion of the forming operation'the driver Vmovesdownwardly and the lower edgea115 of blade V thereon engages thebeveled portion11'5 on the member vU,' caus-'. ing the'member .U torecede from position.

shown in Fig. 24: until a position shown in Fig. 26 is attained;Following" this the cen-',

tralrportion of the staples are guided downwardlyover the beveledportion122 of'memher U, while the ends, 6, of the staples areguideddownwardly through the slots 118 in member The central portionsofthe staples while they are so movedare held in the grooves 120 ofmember V. Thus the engagement of the driver with the staples forces theends a, e,.-through the matter Xnto be stapled, and the lower ends arebent inwardlycby reason of their engagement with the beveled portion 69:in theclincher, asshown in Fig. 19. 'The ends of the staples are thereafter. bent upwardly by the upward movement of the clincher intoclose-engagement with'the matter X, as shown in Fig. 20.

Immediately following the release "of the member U from bar 114 byreason of the engagement of the driver blade with theportion 115, theslide 108 together with the member U which is pivotally held thereon,moves downwardly into contact with the matter X to be stapled an'd'theengagement of the portion 115 of member; V with the beveled portion 122of member U causes said member U to recede outwardly from below thedriver and to the position shown in Fig. 34, so as to permit theapplication ofsufficient pressure to the matter X' and the staple toeffect the driving of the ends 6, e, of the staples through said matterand the clinching theerof, as shown in Fig. 20. As the member U recedesfrom its position between the portions 6, e, of the staple it serves asa support for the staple to prevent the buckling thereof and to in surethe application of the full power of the member V to the staples in adriving operation. n v

Following the clinching operation the members 108, V and U begin theirmovement upwardly for a succeeding operation and the following. thecutting operamember U.moves inwardly to normalfpositionas the driverVjmoves upwardly by reason 1 of the engagement. of the portion 127" ofmember U with the portion 126 ofmemberV. I p 1 During the driving andforming operations the slide 108 having moved downwardly, together withthe member U, which'is. pivotally held: thereon, the upward movement ofthe members U and 'V will effect the restoration of the slide 108 andmember U by means of the engagement ofthe lower ends ofthe groove 125onv member U with the ribs 124 on the slide 108. 1

/ In therestoration of said members as described, when the members U andV have reached a position in their upward travel above the wire feedingpassage 155, the-rollers R and R become operative for initiating thefeeding of a succeeding portion of wire through said passage into theposition shown inFig; 21, preparatory to another operation;

The feeding-operation isaccomplished inthe manner hereinbeforedescribed, and is entirely completed before the members U and V becomeoperative for a succeeding operation.
